Application filed July 3, 1914. Serial No. 848,763.

To all whom it may concern: Be it known that I, FRANK LOWRY, a citizen of the United States, residing at Loudonville, in the county of Ashland and State of Ohio, have invented certain new and useful Improvements in Grease-Superheaters, of which the following is a specification;

The invention relates to means for superheating grease, oils and other kinds of lubricants for feeding the same into the supply line or steam chest of an engine in proper jacent to the steam line; and by providing a chamber around the coil having communication directly with the steam line, as illustrated for a preferred embodiment of the invention in the accompanying drawings, forming part hereof, in which-- Figure l is an elevation section of the improved superheater; Fig. 2, a plan section of the same on line 2- 2, Fig. 1.

Similar numerals refer to similar parts throughout the drawings.

In the improvement of the invention illus trated, the grease pipe 1 is connected by the union 2 with one end 3 of the differential T- fitting 4; the larger end f which fitting is connected with the steam line 6 by the short" nipple 7, and the enlarged stem 8 of the fitting is connected with the lower end of the cylindric case 9, which case has the head 10 on its upper end to form the closed superheating chamber 11 opening only downward through the fitting 4 and the nipple 7 into the supply line 6. The grease tube 12 has one end connected in the smaller'end 3 of the T-fitting whence it extends upward and thence downward to form the inverted U,- shaped coil 13 within the cavity of the superheating chamber 11, whence it extends freely through the nipple 7, and has its open end 14 located within the supply line 6. 'By this simple construction and arrangement it'is evident that sufiicient steam will flow from the steam line through the nipple 7 and upward into the superheating chamber 11,

wherein it will superheat the coil 13 of the grease tube as well as the lubricant passing through the same; it being understood that the water of condensation will flow by grav- 1 ity downward from the superheating chamber and laterally through the nipple 7 back into the supply line.

Inthe operation of the device the grease or other lubricant is supplied or forced unpipe 1 from any'suitableform of lubricant or feeding device; whence it is forced u ward through the ascending branch of t e coil 13 to the summit thereof, where it is met and retarded by the back pressure of the steam rising through the descending branch of the coil from the supply line; and it is evident that the lubricant will be thoroughly heated by'its passage through the coil of the grease tube and especially by reason of its retardation in the ascending branch thereof. The trapping effect of the coil 13, caused by its location above its inlet and outlet ends, prevents the'lubricant from;

being fed into the supply line by gravity and necessitates its being forced upward in a solid column through the ascending branch of the coil, thereby'subjecting it'to the liquefying and vaporizing effect of the surrounding steam and causing it to be fed over and through thesummit of the coil at a rate corresponding to the increased pressure in the grease pipe over that in the supply line.

It is evident that the scope of the invention is not limited to the shaping of the coil as an inverted U as shown, the essential fea ture being that the coil, or some considerable portion thereof, is located above the inlet as well as the outlet ends thereof, and that the same should be located within a superheating chamber adjacent to the steam line, which is preferably heated with steam flowing upward into the chamber therefrom.

I claim:

1. A steam supply line, an adjacent heating chamber communicating therewith, and a grease tube leading into the supply line and having a coil extending above its inletand outlet ends into the heating chamber.

2. A steam supply line, an'adjacent heat- -der pressure, either in a liquid, an atomized or a vaporized condition, through the grease lot ing chamber communicating at its lower end therewith, and a grease tube passing through the lower end 0 the heating chamberiinto the steam supply-line and having a coil extending upward into the heating chamber. 3. A steam supply line, an adjacent heating chamber communicating at its lower end therewith, and a ease tube passing'through the lower end oi the heating chamber into the steam supply line and having an inverted U-shaped coil extending upward into the heating chamber.

4. A steam supply line, an adjacent heat ing chamber, a mpple connecting the lower end of the chamber with the supply line,

and a grease tube extending through the lower endof the heatin chamber and the nipple "into the supply ine and having a coil extending upward into the heating chamber. 3 v

5. A steam supply line, an adjacent heatinto the supply line and having an inverted U-shaped coil extending upward into the heating chamber.
